Answer:
Y = 59.0°
Step-by-step explanation:
Using the cosine rule in terms of x, y and z
cosY =
with x = 22, y = 20 and z = 18
cosY =
=
= , thus
Y = ( ) ≈ 59.0° ( to the nearest tenth )
The correct answer is A. 109 degrees.
Explanation:
Because the angles are supplementary, their sum is 180 degrees.
We know that one of them is 71 degrees, so we substract that from 180, therefore the other angle is 109 degrees.
Answer:
The actual wheel would be : 2 x 12 =24 (cm)
There are g(f(x)) and f(g(x))
do them then evaluate
lets say
f(x)=3x
g(x)=9x^3-4
g(f(x))=9(3x)^3-4=243x^3-4
f(g(x))=3(9x^3-4)=27x^3-12
we can see that g(f(x)) with yield a higher value for x=10
Answer: No
